REAPlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 588,850, dated August24, 1897.

Application filed June 17, 1896.

To all whom, it ntay concern:

Be it known that I, MIHAIL ALEXANDRESCU, a subject of the King ofRoumania, residing at Bucharest, in the Kingdom of Roumania, haveinvented new and useful Improvements in Reaping-Machines, of which thefollowing is a specification.

My invention relates to an improved construction of reaping-machines (inparticular for cereals) which, instead of being propelled bydraft-animals, as heretofore, are propelled by hand.

I will describe the construction of the said machine with reference tothe accompanying drawings, in which- Figure 1 shows a side view; Fig. 2,a plan; Fig. 3, a cross-section on line x y, Fig. 1; Fig. 4, adiagrammatic view of the machine in the operating position.

As shown on the drawings, the machine consists of a framing a of oblongrectangular form, which rests on the wheel-axle b. This axle b iscarried by two road-wheels c and d, of which the first, which is fixedon the axle b, is formed with oblique ribs on the periphery in order, onthe propulsion of the machine, to prevent any slipping of the wheel onthe ground.

The axle 11 carries a chain-wheel e, which may be fixed either to the,wheel '0 or to the axle b, and consequently revolves with these. Themotion ofthis chain-wheel e is transmitted through a pitch-chain f to asecond chainwheel g, loose on the shaft h, but connected thereto by aclutch t'. This shaft carries a bevel-wheel is, gearing with abevel-pinion Z, fixed on a shaft m, which at its front end has a crankm. By means of this crank the knife-bar n at the front end of themachine has a reciprocating motion imparted to it; The knife-bar is ofknown construction. It

carries three-sided blades, which slide to and less cloth p, which, onthe rotation of the said roller, is made to travel across the ma- SarialNo. 595,844. (No model.)

chine. On that side of the machine at which the shaft m is mountedparallel to the longitudinal beam at of the framing is provided a rackg, which can turn with a vertical axis mounted in bearings at the rearend of the machine and whose prongs on the turning of the rack passbelow the cloth 1), traveling over the rollers 19 p. This rack receivesits motion from the road-wheel c, a tappet on the inner side of thewheel-rim being made to act on the levers s, s, and s and thus to impartthe abovedescribed motion to the rack. As shown on the drawings, therack q receives an inward motion at each rotation of the wheel 0.

On the axis of the rack is mounted a helical spring 25, which effectsthe turning outward of the rack after each inward motion. The inwardposition of the rack is shown in dotted lines at Fig. 2.

The machine operates as follows: The op erator, seizing the handles a atthe rear end of the machine, raises this end until the knife andfingerbars in front are situated a certain short distance from the soil,as indicated at Fig. 4. On then pushing the machine forward theknife-bar receives its reciprocating motion by means of the crank-shaftm, as

above described, thereby cutting the stalks of the cereals which fallonto the cloth p. In consequence of the lateral motion hereof the cornis delivered on the rack and accumulates there until the inward motionof the rack produced by the road-wheel 0 causes the corn to be pushedoff the rack in such quantities as to correspond to sheaves, which arethen bound by hand.

In order that during the inward motion of the rack the cut stalks maynot be carried under the rollers 19 19, there are provided on thelongitudinal beam at of the framing bars '12, which on the inward motionof the rack stop the corn and push it off the rack.

In front of the rack in the direction of the knife-bar is provided aguard-platew for the IOO Having now particularly described andascertained the nature of my said invention and in what manner the sameis to be performed, I declare that What I claim is- 1. A reaper orharvester, comprising a frame, two wheels upon which the frame ismounted, a cutter on .the forward end of the frame, a shaft extendedalong one side of the frame, means for rotating said shaft, a connectionbetween the shaft and cutter whereby the cutter is operated, an endlessapron movable transversely over the frame, a rack mounted to swing onthe frame below the plane of the apron, the said rack being normally atone side of the apron, but movable underneath the same, the said rackbeing moved in one direction by one of the supporting-wheels, and aspring for moving the rack in the other direction, substantially asspecified.

2. A reaper or harvester, comprising a carriage, a cutter on the forwardend thereof, means for operating the cutter, an endless apron movabletransversely over the carriage, a rack normally at one side of, butmovable below the apron and actuated in one direction by one of thecarriage-wheels, and a spring for moving the rack in the oppositedirection, substantially as specified.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
